Meanwhile, GUN Commander Abraham Tower enlisted Team Dark and the Spider Troupe to invade the New Black Comet and set a detonator to nuke it, (the exact tactics directed by Dr. Julian Snively). Despite some complications, they were able to succeed in their mission. However, one of the Black Arms, Eclipse the Darkling, and new race named Dark Arms, managed to escape the explosion and landed on Angel Island. Having determined this, G.U.N. dispatched Team Dark with a Tele-Pod that allowed Snively to communicate with them to the island to locate and finish Eclipse and his charges. When it became evident that Eclipse intended to seize the Master Emerald, Snively ordered Team Dark to relocate it to a G.U.N. facility, something that Shadow agreed to but was thwarted in by Knuckles the Echidna. Eclipse subsequently managed to seize the Emerald, only for Knuckles to shatter it to keep it away from him and G.U.N. Eclipse managed to escape in a G.U.N. craft used by Team Dark to travel to the island, while G.U.N. forces later arrived to transport the remains of Eclipse's ship to a secure facility.

Crystal Desert G.U.N. unit fallowing Metal Sonic ambush.

A G.U.N. unit later located the last of the seven Chaos Emeralds being sought by the Freedom Fighters and Dr. Eggman, and communicated word of their find to the Freedom Fighters. Unfortunately, the group was then attacked by Metal Sonic, who overpowered them despite their brave efforts to stop him. The Freedom Fighters arrived in time to provide help and contacted G.U.N. for other personnel to take care of the wounded. (SU: #75)
